Specification of Letters Patent. y Patented Feb, 1.5i, 1916.

Application flied May 1o, 1915. serial No. 27,049.

- To all whom it may concern Be it known that I, FREDERICK J. FISHER, acitizen of the United States, residing in the city and county of SanFrancisco and State o f California, have invented new and usefulImprovements in Molcling-lvlachines,

of which the following is a specification.

This invention relates to a molding machine. i One ofthe objects of thepresent invention is'to provide: a s'imple,.sub stantial land easilyloperated molding machine which 'in this instance is particularlydesigned for molding'meat cakes or Hamburger steak.4 Another object ofthe invention is to provide a hopper into which the 4material to bemolded is placed; and to provide means, such as a plunger, forcompressing and forcing the plastic material out of the container; andto provide a movable molding plate which is adapted tobe brought intoor' out of register with a plurality of discharge openings formed inthebottomof the container.

Another object of the invention is to provide means for readily removingthe molded material from the molding plate.

Further objects will hereinafter appear.

The invention consists Vof theparts and the construction and combinationof parts as v`hereinafter more fully described and Y claimed, havingreference to the accompany- Figure 1 is a plan view of the mold. Fig. 2is a vertical, longitudinal section of the saine. Fig. 3 is a crosssection. Fig. l is a plan View of the molding plate.

More particularly described, Aindicates in general a base or support,consisting of a pair ofconnected standards 2, upon which is mounted arectangular-shaped hopper 3.

c Adapted to be raised and lowered within said hopper, by ymeans of ascrew rod 4C, is a plunger 5; the rod and plungerbeingsupported by apivotally'mounted cross bar 7 which may be'swung to one side when it isdesired to clean or reill the hopper.

Formed in the bottom of the hopper is 'a plurality ofv dischargelopenings 8, land mounted below said openings is a molding plate 9 inwhich is formed a plurality of openings 10 which are normally inregister with the discharge openings 8 formed in the .bottom ofthehopper. The molding 55 :plate Y. is, iin thijs instance-,'provided onits lower face and outer edges with a pair of raclr bars 11. one voneach side ofthe plate, and these bars are in turn positioned so as tointeimesh with a pair of pinions 12 jou-r- Analed upon yshafts 13, therebeing one pair of shafts and four pinions, two on each Side of theplate. One of the shafts 13 `is provided with a liand-wheel lll by whichthe :shaft and pinions-may `be turned to move the molding plate as willhereinafter Vbe described. Pivotallyr mounted, as at 14,0n the lowerside of the molding plate is a platform 15 which is normally adapted toform a closure for the openings 10 formed in the molding plate. Platform15 is ,adapt-4 ed to be raised and lowered `with relation to the moldingplate, or, in other words,

'it is only necessary to rotate vthe 'screw by means of a hand-wheel 17.`This'willfc'auseV the plunger toniove in a downward direction and forcethe materialthrough the 'discharge openings into the registeringopenings 10 inthe molding plate." After these openings'have becomevfilled or charged, it!

is only necessary'to turn hand-wheel 14 in a direction lwhich will causethe rack bars,

Aswung about pivot 14: and is normally held with connected moldingplate, to move for-.- ward intol the dotted line position indicated at18. Latch 16 is here released andthe platform 15 is permitted to dropinto the inclined position indicated at 19. The plas-v .tic materialhaving a tendency to adhere to this :plate will thus bev extracted fromthe openings inthe molding plate and may here -be removed Afrom theplatform in any 'suitable mannen l n Y A For the purpose'of preventingthe plastic material from adhering to the face' of platform 15, and alsoforthe purpose of quickly removing theV molded articles. a thin sheet svil 0 5 rection. Formed on one end of the .molding Aplate is anextension 20. This is only provided for the purpose of closing thedischarge openings 8 in the bottom of the hopper when the molding plateis moved forward to remove the plastic ormolded` Ymay be wiped out asoccasion and conditions demand, thus preventingthe machine rand supportfrom becoming soiled or contaminated. The materials and finish oftheseveral parts of the machineiare otherwise'such as the experience andjudgment of the manufacturer may dictate.

I wish it understood that -various changes in form, proportions andminor details of construction may be resorted to within the scope oftheappended claims, and that I do not wish to limit myself to thespeciiicdesi gaand construction here shown.

Having thus described my invention, what I claim and desire to secure byLetters Patent is l. In a Ymolding machine, a hopper having a pluralityVof discharge lopenings formed therein, a molding plate slidably mountedunder the hopper, said plate having openings formed therein adapted toregister with the openings in the hopper, a platform platek pivotallymounted Von the lower lside of the molding plate, and: means for movingsaid plates in `unison-,to bring the mold plate openingsinto and out ofregister with the discharge openings in the hopper.

2. In `a molding machine, a hopper vhaving va plurality of dischargeopenings .formed :therein a molding plate slidably mounted under thehopper, said plate having open-` ings formed therein adapted to registerVwith the openings inthe hopper, a platform'plate pivotally .mounted onthe lower Yside of the molding plate, means for moving said plates inunison torbring the mold plate openingsinto and out of register `withthedischarge openings `in the hopper, and means for exerting'fpressureon the contents 2of fthe hopper Vto :lill the openings in themolding'plate. i

`V3. In amolding machine, a'hopperchaving a plurality of dischargeopeningsformed therein, a molding plate slidablymounted 4underthehopper, said z plate lshaving Aopen ings formed therein adapted toregister with the openings in the hopper, a platform plate pivotallymounted on the lower side of the molding plate, means for moving saidplates in unison to bring the mold plate openings into and out ofregister with the discharge openings in the hopper, and

means for. locking the platform plate with relation to the moldingplate.

4. In a molding machine, a hopper having a plurality' of rdischargeopenings formed therein7 a molding plate slidably mounted under thehopper, said platek .having `openings formed therein adapted 4,to

register with the openings in the hopper, f2 a vplatform plate pivotallymounted on thel lower side of the'molding plate, means foi moving saidplates in unison to bring `the *y mold plate openings into and out ofregis-` ter with the discharge openingsA in the hopper,means for lockingthe platform 4plate with relation to the molding plate, and" means forexerting pressure onv the contents frame, said hopper having a:plurality of 1 discharge openings formed gin= the bottom,
